VARIABLE WIRELESS POWER TRANSMITTER INCLUDING PLURAL RESONATORS AND METHOD OF CONTROLLING THE WIRELESS POWER TRANSMITTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17987590 titled 'VARIABLE WIRELESS POWER TRANSMITTER INCLUDING PLURAL RESONATORS AND METHOD OF CONTROLLING THE WIRELESS POWER TRANSMITTER
Simplified Explanation
The patent application describes a variable wireless power transmitter that includes multiple resonators and a method for controlling it. Here are the key points:
- The wireless power transmitter consists of a housing, a power amplifier, and two resonators.
- The first resonator is fixed to a portion of the housing and includes at least one coil.
- The second resonator is rotatably disposed at another portion of the housing and also includes at least one coil.
- The second resonator can be adjusted to form a variable angle with the first resonator.
- A sensor is used to detect any shape change resulting from the rotation of the second resonator.
- A controller analyzes the sensor signal to identify shape changes in both resonators and determine if the impedance is matched.
- If the impedance is not matched, the controller generates a control signal for impedance matching.
- A matching circuit, consisting of coils and capacitors, is electrically connected between the power amplifier and the first resonator.
- The matching circuit performs impedance matching based on the control signal received from the controller.
Potential applications of this technology:
- Wireless charging systems for electronic devices such as smartphones, tablets, and wearables.
- Power transfer systems for electric vehicles, allowing for convenient and efficient charging.
- Industrial applications where wireless power transmission is needed, such as automation and robotics.
Problems solved by this technology:
- Ensures efficient power transfer by continuously monitoring and adjusting the impedance between the resonators.
- Allows for flexibility in positioning and alignment of the resonators, improving the overall user experience.
- Provides a solution for impedance mismatch, which can lead to power loss and reduced charging efficiency.
Benefits of this technology:
- Enables wireless charging over variable distances and angles, providing convenience and flexibility.
- Optimizes power transfer efficiency by dynamically adjusting the impedance between the resonators.
- Reduces the risk of power loss and improves charging speed by ensuring impedance matching.
- Enhances user experience by allowing for easy alignment and positioning of the charging device.
